VARIABLE-SPEED REVERSING MECHANISM.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed January 1c, 1908. semi No. 411,124.

To all whom it may concern:

Be it known that I, CHARLES EDoUARp HENRIO'D, a citizen of the Swiss Confederation, and resident of Neuilly-sur-Seine, France, have invented new and useful Implrovem'ents in or Relating'to Variable-Speed eversing Mechanism, which improvement is fully set forth in the following specification.

The present invention relates to atransmitting mechanism and (particularly to an improvement on the-one plication Ser. No. 364,577, filed March 26t 1907. In that application the mechanism which is designed to allow different changes of speed and reverse drive consists of a fly wheel system comprising a motor shaft, a fly 'wheel, planetary wheels and a driven shaft,

andiin which the chan e of s eed is obtained by the direct braking o the p anetary wheels. Thezpresent invention has for its ob'ect to provide a fly wheel system which su stantially comprises the same elements, but in which, instead of by direct braking of the planetary wheels, the change of speed is obtained by the action of idle wheels.

Theinechanism can be used for various industrial pur oses but it is chiefly intended to be used m t e motor car industry.

In order to make m invention more clear the same is illustrate in the accompanying drawings, in which similar reference charac ters denote correspondin parts and in.

fly wheel. 2 is the second part thereof, which incloses the gear for changin the speed and which can be coupled wit the part 1 by means of the clutch cone 3. 4 is the central spindle to be driven. This s indle ma transmit its movement to a vehicle, a vesse or any other machine. Keyed to or rigid with sand central spindle is a toothed crown 5 provided with notches 5', into which the extremities of a claw 5 enter'at the moment of direct engagement. The crown 5 in escribed in my ap: I

which rests the clutch cone 3 and by the present example has its teeth on tlie'inside, but, evidently, the same could have the teeth just as well on the outside, in which case it would act upon the inside of the satellite wheels to be hereinafter described. Journaled in the art 2 of the fly wheel and in a disk 6 which is' oosely mounted on the shaft 4 are spindles 6 which carry systems of idle satellite wheels. Each system may comprise any suitable number of such wheels.

11 practice three wheels will suffice. In the present example each system consists of the Wheels 7, 7, 8 and 9 of difi'erent diameters. Of these'wheels, 8 serves for the reverse movement, 9 for the third speed, 7 for the intermediate speed and 7 for the first speed. Mounted upon the central s indle 4 are nonrotary sleeves a and b whic are capable of longitudinally slidin thereon. The sleeve 0- which can be displaced by aetin r on the pins 47 carries a toothed wheel 10, w 'ch, ac-

cording to the position'it occupies upon the spindle 4, enga es either diretly with the wheels 7 (for the forward movement), or,

for the reverse movement, with the wheels 43, which mesh with the wheels 8 of the satellite systems. displaced by actin upon the pins 11 carries two toothed whee s 44 and 45. According to the position occupied by the sleeve 1) upon the spindle 4, the wheel 45 will engage with the wheels 9 of the satellite systems or the wheel 44 with the wheels 7 thereof. Along the s indle 4 and on the outside of the sleeve a, a caring 22 is slidably mounted, upon the displacement of which the parts 1 an 2 of the y wheel can be either coupled with or uncoupled from one another. The art 3 carries inside keys or projections 24 slidably engaging grooves 23 formed on the outside of the part 2 of the fly wheeL' The outer surface of the cone 3 acts by friction against the part 1 of the fly wheel. Secured to the part 2 of the fly wheel are guide rods 14 bearing springs 48 which constantly tend to bring part 3 into engage ment wit part 1.

The mode of operation is as follows Supposing that the fly wheel is applied to a motor of an automobile vehicle, and that the motor is workin while the vehicle is at rest. In this case t e cone 3 is thrown out of engagement and none of the toothed wheels 10, 44 and 45 of the sleeves is in enga ement with the toothed wheels of the satel ite systems. Hence, the spindle 4 which, in this case, is the The sleeve b which can be motor.

spindle driving the vehicle wheels, is at rest. When it is desired to start the vehicle the sleeve a is displaced until the toothed crown 10 thereof engages with the toothed wheel 7. Thereupon the cone 3 is thrown into engagement, so as to couple the parts 1 and 2 of the fly wheel. By this manipulation the part 1 of the fly Wheel, which revolves with the motor, sets the part 2 by means of the clutch cone 3 in motion, and the spindles 6 of the satellite systems describe a rotary movement around the spindle 4. Since, however, the wheels 7' mesh with the non-rotary wheel 10 of the sleeve (1, the wheels of the satellite systems also turn around themselves and the wheel 9 thereof which meshes with the toothed wheel 5, causes the latter to revolve which being keyed to the spindle a, sets the latter and consequently the wheels of the vehicle in motion. When it is desired to pass to the second speed the cone 3 is thrown out of en gagement and the sleeve a is moved so as to disengage the wheel 10 from the wheel 7. Thereupon the sleeve 5 is displaced training the wheel 44-. in engagement with the wheels 7 and the cone 3 is again thrown into engagement, whereby the spindle 4 is caused to revolve in the same manner as before but with a greater speed. in order to pass to the third speed the cone 3 is thrown out of en gagement and the sleeve 5 displaced until the wheel 45 engages with the wheels 9 of the satellite systems. Thereupon the cone 3 is returned, whereby the spindle 4 is set in motion the same way as before but-with a still higher speed. In order to have the vehicle run with the same speed as that of the motor, the sleeve 1) is shifted inward to the full of its lon itudinal movement, so as to act against the c aw 5", bringing the latter into engagement with the apertures 5 of the crown 5 connecting the latter with the support 6 of the spindles 6 of the satellite systems; In consequence thereof the spindle 4 is caused to revolve with the speed of the This constitutes the direct enga ement. Sprin ss automatically cause the isengagement 0 the claw 5. from the apertures 5 as soon as, in order to discontinue direct engagement, the sleeve 7) is moved from left to right. The backward movement is effected, as will be seen, by bringing the wheel 10 of the sleeve a into enga ement with the intermediary wheels 43 whic mesh with the wheels 8 of the satellite systems.

Fig. 2 shows a modification of the above described apparatus, in which the wheels of the satellite systems are always in engagement with the wheels of the sleeves which in this case are loose and which, in order to produce the diflerent speeds, can be rendered immovable as will be hereinafter described. The parts 1, 2 and 3 of the apparatus are the same as those of the one described and need not be again explained in detail. With the construction shown in this figure we can ob constantly engages with the,wl1eel 18 that is.

loosely mounted upon the shaft 4 and serving for the second speed and the wheel 15 constantly engages an intermediary toothed wheel 15 (as seen from Fig. 2 the axles 15 "of which are sup orted in the same manner in the parts 2 of t e fly wheel as the axle 6 of the satellite wheels, which mesh with the loose wheel 19 mounted on the shaft 4 and serving for the backward movement. The

wheel 16 constantly engages with the wheel 20 which is rigid with the shaft and which serves for the transmission of movement to the latter. The loose wheels 17 and 18 are centered by the wheels of the satellite systems distributed around them (Fig. 2), while the wheel 19 is centered by the intermediate wheel 15 (Fig. 2 Slidably mounted on the shaft 4 is a non-rotary sleeve a which is formed with a projection 21 that serves as a key and isv adapted to engage according to the position of the sleeve 0. with any one of the wheels 18, 17 or 19. When the sleeve 0/ is shifted to the right, in the direction of the arrow as, to the full stroke of its movement it is caused to act by means or its projection 21 against the claw 25 capable of swinging upon the pivot 26 and causes the same to engage the notches 27 rovided in the satellite wheels, and to there y hold the latter stationary upon their spindles 6. Suppose that the motor revolves, that the cone 3 1s disen aged and that the key 21 is in the position s own in Fig. 2. The shaft 4 is then at rest; In order to set it in motionwith the first speed the sleeve a. will be shifted in the reverse direction of the arrow 0;, until the key 21 will engage the idle wheel 17 holding the latter stationary. Thereupon the parts 1 and 2 ofthe fly wheel are clutched by the cone 3, whereby the part 2 will be caused to revolve with the speed of the'motor. The spindles 6 of the satellite wheels will be carrled around the shaft 4, and as the wheels 13 of the satellite systems engage with the sta-.

. lever (not shown), enlgla of parallel thereto.

.29 and 29 are loose upon the s indle.

the cone 3 which, as in the preceding example, will cause the transmission of movement to the shaft 4 with a difierent speed, therotation of the satellite systems upon their spindles being now effected by the wheels 12, 16 and 20. i To obtain backward movement the sleeve a is shifted to the left until its key 21 engages with the Wheel 19 and holds the same stationary. As mentioned above this wheel '19 constantly engages with intermediary'toothed wheels (not shown in the drawing) which mesh with the wheels 15 of the satellite system. Finally for the direct engagement, the sleeve a is shifted in the di rection of the arrow at until its key 21 strikes the claws 25, swinging the latter upon their pivots 26 and causing them to engage into the notches'27 of the satellite systems, whereby the latter become looked upon their spin- (lles 6. In consequence thereof, when parts 1 and-2 are coupled by cone 3, the s eed of the motor will be directly transmitte to theshaft 4 by the wheels 16 and the wheel 2 which is keyed to the shaft 4.

In Fig. 3 a second modification of the aparatus is shown. In rinciple this modication conforms wit the construction shown in Figs. 1 and 2, and the function thereof is also the same as in the two receding examples. The only difference ere is that the spindles 6 of the satellite wheels are perpendicular to the driven-shaft 4 instead This apparatus allows three speeds (forward movement). Mounted upon each spindle 6 of the satellite systems are threeconical inions, of which one 29 is keyed to the spin e 6" and constantl meshes with the central wheel 32 which is eyed to the shaft 4. The two other satellite \Vh ijfiS e pinion 29 constantly meshes with the wheel 33 and the pinion 29 with the wheel 33', both of these wheels 33 and 33 being formed upon the same plate which is provided with a non-rotary sleeve 11 surrounding the driven shaft 4 and carryin projections 11. Slidably mounted upon eagi spindle 6 is a friction clutch 28 which can be brought to engage either with the wheel 29' or the wheel 29" and to accordingl lock the same to the spindle 6. The clutc is secured to the end of a rod 31, the other end of which engages a cam groove 31 provided in a block 31.-

The latter is formed on the end of a nonrotary sleeve 0, which is slidably mounted on the shaft 4. The displacement of the sleeve a can be effected by means of a forked ing the collar 49. When the sleeve a is s ted to the left sufficiently to cause by the cam groove 31 in the block 31 the movement of the clutch 28 until it engages with the wheel 29 looking the latter u on the spindle 6, in consequence thereof t e rotary movement of the wheel 29' which is imparted thereto by the stationary wheel 29- and wheel 32 rotary motion of a certain speed will be transmitted to shaft 4. When the sleeve 0/ is shifted to the right the clutch 28 will be caused to engage with the wheel 29", in consequence of which a different s eed will be transmitted to the shaft 4. For direct en agement the sleeve a will be shifted to theleft until its block 31 will cause the spring actuated slidable claw 34, that normally engages notches 35 in the wheel 32, to enter notches 36 in-the inner part 2 of the fly wheel. In consequence thereof the part 2 becomes directly coupled with the shaft 4 and transmits to .the latter movement with the speed of the motor. This constitutes the. direct engagement. By the shifting of the sleeve a to the left for the direct engagement the clutch 28 will also key the wheel 29 upon its spindle, but this has no effec on the direct transmission. 1
